20120230390 | Adaptive Control of Encoders for Continuous Data Streaming - Active control of the output bit-rate of a system of constant bit-rate encoders is provided to match their aggregate bit-rate to the available network bit-rate of a communication channel over which a packetized data stream is to be transmitted. Cross-layer optimization is achieved between network layer performance metrics, such as queue size, round-trip-time delay, and available bit-rate, and application layer requirements of the data encoders, such as output bit-rate, input frame-rate, and packet loss, through a tight coupling of these parameters. Complex run-time calculations or heavy network probing are avoided while achieving the beneficial results, which is advantageous in systems that deal with real-time applications, such as live video streaming for video surveillance and security. | 09-13-2012 |

20120094564 | STAINPROOFING METHOD OF FABRIC - A method for anti-stain treatment of fabric is disclosed. The method for anti-stain treatment of fabric includes: immersing fabric in an aqueous solution containing a telomerized perfluoroalkyl acrylate copolymer, and a crosslinking agent, such as an isocyanate crosslinking agent; dehydrating the immersed fabric; drying the dehydrated fabric; heat treating the dried fabric; and coating the heat-treated fabric with a flame retardant, such as an acrylic flame retardant, to provide flame retardancy. The method provides a car seat fabric having superior stain resistance, water repellency and oil repellency without degradation of other properties required for the car seat fabric, such as flame retardancy, lightfastness, frictional coloration, or the like. The method is widely applicable to commercially applicable car seat fabrics, including flat woven, flat tricot, double raschel, or the like. | 04-19-2012 |
20120308726 | METHOD FOR PRODUCING SYNTHETIC LEATHER HAVING AIR PERMEABILITY - Disclosed is a synthetic leather produced by directly coating a water-soluble synthetic resin solution on the surface of a fabric to form a film thereon such that fine gaps formed on the fabric are partially left open to have a certain degree of air permeability. In particular, a brushing process is used for brushing the surface of a fabric using a brushing machine to raise a nap. Next, a hydrolysis-resistant and flame-retardant resin solution is coated on the back of the fabric, which is opposite to the surface on which the nap is raised, to reinforce the back of the fabric. A film forming process then applies a water-soluble polyurethane resin solution to the nap raised on the surface of the fabric to form a film on the surface of the fabric thereby producing a synthetic leather product that has air permeability properties that are superior to genuine leather. | 12-06-2012 |
20130263383 | VEHICLE SEAT COVER LEATHER HAVING EXCELLENT DURABILITY AND METHOD OF FABRICATING THE SAME - Disclosed is a method of fabricating an automotive seat cover leather. The method includes a preparing process, a tanning process, a neutralizing process, a retanning process, an elastic material adding process, a dyeing/fatliquoring process, and a surface fixing process. After the leather has gone through the tanning process and neutralizing process, the retanning process adds a tanning agent to the leather. The elastic material adding process adds a silicon-based elastic material to induce elasticity in the retanned leather. The dyeing/fatliquoring process adds a dye to the leather in which the elastic material has been added and adds an anion fatliquoring agent to the leather to provide flexibility. The surface fixing process fixes the elastic material, dye, and fatliquoring agent on and in the leather. | 10-10-2013 |
